Indoor Unit
Installation
If there is no refrigerant piping embedded in
the wall,
do the following:
Fig. 4.7
Fig. 4.8
Step 3.
Connect drain hose and refrigerant
piping (refer to
Refrigerant Piping Connection
section of this manual for instructions).
Step 4.
Keep pipe connection point exposed to
perform the leak test (refer to
Electrical Checks
and Leak Checks
section of this manual).
Step 5.
After the leak test, wrap the connection
point with insulation tape.
Step 6.
Remove the bracket or wedge that is
propping with insulation tape.
Step 7.
Using even pressure, push down on the
bottom half of the unit. Keep pushing down
until the unit snaps onto the hooks along the
bottom of the mounting plate.
1. Based on the position of the wall hole relative
to the mounting plate, choose the side from
which the piping will exit the unit.
2. If the wall hole is behind the unit, keep the
knock-out panel in place. If the wall hole is to
the side of the indoor unit, remove the plastic
knock-out panel from that side of the unit.
(See
Fig. 4.9
). This will create a slot through
which your piping can exit the unit. Use
needle nose pliers if the plastic panel is too
difficult to remove by hand.
3. Use scissors to cut down the length of the
insulating sleeve to reveal about 40mm (1.57in)
of the refrigerant piping. This serves two
purposes:
•
To facilitate the
Refrigerant Piping
Connection
process
•
To facilitate Gas Leak Check
s
and enable
you to check for dents

3. Use the holder in the mounting plate to
prop up the unit, giving you enough room
to connect the refrigerant piping, signal cable,
and drain hose.
